Import Tips
• Obtain visual inspection certificates confirming RSS 1 cleanliness standards; even minor discoloration can downgrade classification
• Declare exact sheet thickness and smoking process details; ensure no surface-working beyond simple cutting to rectangular shapes
• Check for proper PE wrapping to prevent contamination during shipping, as exposed sheets risk reclassification as scrap
